That's exactly why it seems rather unreasonable; to get testy with me for not being privvy to something privileged? Assuming that hypothetical 'something' does exist.

If M are actively working on such a thing, it would be really helpful to be given a heads-up. For example, would such a solution enable integration of track level data to albums already ripped, without affecting carefully groomed metadata already there, etc., or are we doomed to rip our entire catalogue again?
